PATENT @i ldiifillie GEORGE J. BERBERT, OF NEW YORK, N. Y.

AIR-BR-AKE-OPERATING DEVECE.

SPECIFICATION forming part of Letters Patent No. 753,114, dated=February 23, 1904,

Application filed January 8, 1903.

To all whom it may concern.-

Be it known that I, GEORGE J. BERBERT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Air-Brake-Operating Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains'to make and use the same.

The object of this invention is to provide an improved automatic device for operating the air-brakes of a railway-train if at any time such trains should pass a danger-signal which is for any reason not seen or observed by the engineer, a further object being to provide an automatic air-brakeoperating device or devices particularly adapted for use in railwaytunuels, but which may be employed at any point along a railway track or line, part of the device or devices being connected with the cab of the engine and the other part consisting of a semaphore-signal or other device such as is now usually employed.

. In the drawings forming part of this specitication, in which the separate parts of my improvement are designated by the same reference characters in each ofthe views, Figure 1 is a side view of the rear portion of a railway-engine and the front portion of the tender provided with my improved brake-operating device, and Fig. 2 a rear view of the engine and showing the semaphore or signal device which t'orms a part of the apparatus which I employ.

My improvement is in practice applied to an ordinary air-brake apparatus such as is now employed on railway-trains, and in the drawings forming part of this application I have shown at a the cab of a railway-engine and at b a portion of the tender.

The engine a is proxidcd with the usual compressed-air tank 71 which is in communication, by means of a pipe 0, with the brake-operating apparatus beneath the tender and be neath all the cars of the train, said cars being not shown, and a pipe (Z is also in corhmnni cation with the air-cylinder b and leads up into the cab of the engine and is under the control of the engineer by means of a valve Serial No. 138,190. (No model.)

e or in any other way, all these parts being of the usual'form and construction; but the pipe cl and valvee form no part of this invention, all that is necessary being to connect the pipe g with the air-pipe c of the air-brake apparatus. I also connect with the pipe 0 by means, of a coupling f or in any other preferred manner a pipe g, which extends upwardly through one corner ot'the cab of the engine and out at the top thereof, as shown at and this pipe is provided with a branch g with which is connected a valve-casing g, in which is placed a valve g, the upper end of which is provided with 'a stem g, having a horizontal arm g and an upwardly-directed crank member g Another pipe h is connected with the pipe g near the upper end thereof and extends horizontally across the cab under the roof thereof and passes up through the roof of the cab at the side opposite the pipe g, as shown at If, and this pipe is also provided with a valve-casing in which is placed a valve similar to the valve g this valve being also provided with a stem 9, having a horizontal arm g, at the end of which is an upwardly-directed crank met ber 9 In Fig. 2 of the drawings 1 have shown at it one of the side walls of a tunnel, or this may represent any suitable support, and connected therewith at]: is a semaphore-arm it which is adapted to be operated in the usual manner, so as to'signal the engineer in case of danger ahead, and, as is usual with'this class of devices, when said semaphore-arm is at danger, or in the position to indicate danger, it is in a horizontal position, as shown in Fig. 2, and when not in the position to indicate danger it is in a vertical or raised position. The semaphore-arm k is provided with a finger or supplemental arm h, and if at any time it should be in a horizontal position, or in the position to indicate danger, and the engineer should for any reason tail to observe said signal the 'tinger or arm b will strike the member g of the valve-stem g and will turn the valve 5 in the corresponding valvecasing g, and the air from, the air-cylinder will escape.and the brakes of the train be operated in the usual manner.

The arms g of the valves g in the correspending valve-casings g are when in pos for use always lire-owl outwardly, engine is always provide with two of these valve-casings and valves, one being loomed at each side thereof, and the arrangement of the semaphore arm or arms it is always such that as the train passes the valve will be operated as herein described, providing the sig nel or semaphore is in the position to indicate danger.

it will be understoofl that the connections 'be operated by the semaphore-arm if when the latter is in position to indicate danger.

Although I have shown and described my improvement as applied to e railway-engine,

it Will-be apparent that the same may be op galied to any sort of a motor car or vehiole secure by Letters icle eonnesteoi wit tencling upwwdly the S 0e 7 eh i ed valve-oesebove the top U sh vslves laterally-distaste silent/sci to operetecl bj e semaphore {537911 or signal located the side of the trash when in a position to indi cate danger, substantially as shown and de scribe i V In testimony that l claim the foregoing as my invention i have signeclmynen1e,inpresi 'esoribe myinvention, What 7 en use oro- 1 once of the subscribing witnesses, this 6th day of January, 1903.
